Answer:
(D)What did Micah eat for lunch yesterday?
Step-by-step explanation:
A statistical question is a question for which the expected response varies. That is, we do not expect to get a single answer. Out of the given options,
Option D is not a valid statistical question as the response to the question will always be the same for a particular day,
If Micah ate cheesecakes for lunch yesterday, asking repeated times will not change the response.
answer
10
step-by-step explanation
the equation given is sin(x) = cos(y) with x = 2k + 3 and y = 6k + 7
substitute in 2k+ 3 for x in sin(x) and substitute in 6k + 7 for y in cos(y)
sin(x) = cos(y)
sin(2k + 3) = cos(6k + 7)
we know that sin(x) = cos(90 -x)
sin(2k + 3)
= cos(90 - (2k + 3) )
= cos(90 - 2k - 3)
= cos(87 - 2k)
substitute this into the equation sin(2k + 3) = cos(6k + 7)
sin(2k + 3) = cos(6k + 7)
cos(87 - 2k) = cos(6k + 7)
87 - 2k = 6k +7
80 = 8k
k = 10
X=2 or y=-1
these are the points that the graph avoids
